Modern society produces more and more waste materials, with an ever increasing demand for energy and fertiliser whilst facing the challenges of climate change.

Anaerobic digestion and composting are well know methods for the treatment and recovery of wastes containing organic material. A major breakthrough is the successful development of multi-stage anaerobic digestion and composting, the patented Bioplex process. This can treat a variety of food and agricultural wastes, resulting in biogas, natural fertiliser and fibre.

The Bioplex process can include the Portagester ®, a revolutionary new pre-composter and anaerobic fermenter for the treatment of farm and horse stable manures; food and catering wastes; trade, garden and local authority wastes. The Portagester can be used as an add-on to conventional anaerobic digesters or supplied as a complete system.

Depending to some extent upon the type of feedstock being treated, the plant is relatively odourless, clean and compact; sealed vessels prevent cross-contamination and disease risk from birds, rodents and insects.

The fermented and composted solid material can be used as organic fertiliser-rich fibre for soil conditioning and as a growing medium, with the environmental and political advantages of replacing peat and petrochemical based fertilisers. Separated liquid can be treated in an anaerobic digester (AD) to produce biogas - an energy source.

After several years of research and development (see news and updates) and extended testing, the final digesters as products will become available later this year or early next.

Please note that the trading name "Bioplex" and all of the associated IP are now back with Longstock Energy Ltd.
